P10 is active, but Status Screen is empty and now since wave shown

Hi there,

I was changing equipment and had the P10 shut down.

After restarting the P10 it all works, but the “Status Screen” shows now values, also I don’t see the usual Sinewave. I of course restarted P10. Nothing changed.
Andy idea, what this could be?

Thanks for any help / hint.
